GUARD ATTACHMENT FOR CLOTH-SHEARING MACHINES.

Specification of Letters Patent.

Patented May 29, 1917.

"Application filed January 24, 1917. Serial No. 144,244.

To all whom it may concern:

Be it known that I, WESLEY R'VAIR, "a citizen of the United States, residing at Ravenna, in the county of Portage and State of Ohio, have invented certain new and useful Improvements in Guard Attachments for Cloth-Shearing Machines, of which the following is a specification.

This invention relates to an improved guard for a cloth shearing machine and the principal object of the invention is to provide a guard so constructed that it may be positioned in operative relation to the cutting mechanism of the shearing machine and prevent danger of the operators hand hitting the cutting mechanism, the guards being formed in sections, hingedly connected so that one section may be swung out of the way when it is desired to have access to the cutting mechanism for the purpose of making repairs or of making any necessary change or adjustment to the cutting mechanism.

Another object of the invention is to so construct the guard that it may be connected with cloth shearing machines of a conventional structure thus permitting the guards to be connected with machines already in use.

This invention is illustrated in the accompanying drawings, wherein Figure 1 is a view in front elevation showing a portion of a cloth shearing machine with the improved guard in place.

Fig. 2 is a vertical sectional view taken along the line 22 of Fig. 1.

Fig. 3 is a fragmentary view of the improved guard.

Fig. 1 is a perspective view of the two hingedly connected sections of the guard.

This guard is to be used in connection with a cloth shearing machine of a conventional structure and indicated in general by the numeral 10, the machine including a ro tary cutter 11 carried by a movable frame or carriage 12 raised and lowered through the medium of the handle 13. This shearing machine is further provided with a cutter 14 having a handle 15.

The guard is provided with sectlons 16 and 17 connected by hinges 18 so that the upper movable section may be swung out of the way when it is desired to have access to the cutter. Each of these sections is pro vided with frame braced by bars 19 and covered with wire 20 to prevent the operators hand from passing through the guards and into engagement with the cutting mechanism. A slot 21 is provided adjacent the free edge of the lower section to permit of a sheet of paper being passed through the guard for testing the operation of the cutters.

When installing the guard, it is put in place as shown in Figs. 1 and 2 and the stationary section will be connected with the frame of shearing machine by brackets 22. The cutting mechanism will thus be protected and can be raised in order to permit the scam of the cloth to pass thereunder when necessary by grasping the handle without danger of the hand slipping from the handle and striking the cutting mechanism. When it is desired to make any adjustments or repairs, the movable section can be swung out of an operative position and when this is done, the eyes 23 will pass through the slots 24 where they will be engaged by hooks 25 to releasably hold the movable sections in the inoperative position.

I have thus provided a guard which will be very eflicient in operation and which will be so constructed that it may be used in connection with machines of a conventional structure and already in use.

What I claim is 1. A guard for cloth shearing machines comprising sections hingedly connected, each section comprising a frame having transversely and longitudinally extending bracing bars, a fabric covering for each frame provided with a longitudinally extending slot adjacent the longitudinal free edge of one of the frames, means for connecting one of the sections with a cloth shearing machine, the second section normally extended in an operative position, and means for releasably holding the second section in an inoperative position.

2. A guard attachment for a cloth shear- 'ing machine comprising hingedly connected sections, each section having a frame, a fabric covering for each frame, the fabric covering of one frame bein provided with a longitudinally extending sot adjacent the longitudinal free edge thereof, and means for connecting one of said sections with the frame of a cloth shearing machine, the second section normally extending in an operative position and movable to an inoperative position.

3. A guard attachment for a cloth shearing machine comprising hingedly connected sections, one of the sections being provided adjacent the free edge With a longitudinally extending slot, attaching brackets for con necting one of the sections with a cloth shearing machine frame, the second section normally extending in an operative position and movable to an inoperative position.

4:. A guard attachment for a cloth shearing machine comprising hingedly connected 'sections, attachment brackets for connecting one of the sections with the frame of a cloth shearing machine the second section normally extending in an operative position, and means for releasably holding the second section in an inoperative position.

In testimony whereof I affix my signature in presence of tWo Witnesses.
